A programmable metamaterial finger can lock into four positions without electronics, offering a simpler and more functional future for prosthetic hands.
A single piece of metamaterial that locks like a real finger can simplify the design of hand prostheses and robotic grippers, providing users with greater comfort, aesthetics, and functionality at lower cost.
Researchers from several Fraunhofer Institutes are working together on the “ProFi” (Programmable Multistable Finger) project.
